Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490746, here are decompositions:

5 + 490741 = 490746
13 + 490733 = 490746
83 + 490663 = 490746
103 + 490643 = 490746
127 + 490619 = 490746
167 + 490579 = 490746
173 + 490573 = 490746
197 + 490549 = 490746

Showing the first eight; more decompositions exist.
